Für Biertreber, das mengenmäßig größte Nebenprodukt im Brauprozess, soll als Zwischenstand eines laufenden Forschungsprojekts ein über den bekannten Stand der bisherigen Trebernutzung hinausgehender Verwertungspfad vorgestellt werden. Der Fokus liegt hierbei auf einer anpassbaren, selektiven Abtrennung der noch enthaltenen Wertstoffe aus dem Treberpresswasser. Es werden Versuche zur gezielten Abtrennung der Inhaltsstoffe für eine spätere stoffliche Nutzung mittels Mikro-, Ultra-und Nanofiltration vorgestellt. Die Eignung verschiedener Membranen wird dabei basierend auf der erreichten Permeabilität sowie dem Rückhalt von Wertkomponentenklassen wie Proteinen und Polyphenolen bewertet. Es konnte u. a. gezeigt werden, dass bei der Mikrofiltration mithilfe einer rotierenden Membran Permeatflüsse im Bereich der kommerziellen Bierfiltration erreichbar sind.A new utilization concept for brewers' spent grains, the main byproduct of the brewing industry, is introduced. First results from an ongoing research project beyond the actual state of the art of brewers' spent grains usage are presented. It is focused on developing an adaptable selective separation procedure of valuable components from press water arising by mechanical dewatering of brewers' spent grains for the use as food additive. Experimental results on micro-, ultra-and nanofiltration for specific separation of the ingredients focused on substance classes are presented. The membrane applicability is evaluated by the membrane permeability and by the retention of valuable components like proteins and polyphenols. Results showed that the microfiltration of press water with a rotating membrane is comparable to commercial beer microfiltration in terms of permeate flux.

“…Comparisons are most often based on cost, as well as social impacts and environmental effects. Meschke et al [57] studied the use of a rotating microfiltration system for the treatment of AMD produced by opencast lignite mining. They reported that to increase the solid content as well as to remove iron hydroxide from AMD, integration of a rotating membrane module may be considered as a suitable option.…”

Increasing population levels, growing economies, rapid urbanization and changes in consumption patterns have increased the demand for raw materials such as base and precious metals, leading to growing concerns regarding their availability and the global efficiency of the mine supply chain. Mine tailings, consisting of process effluents that are generated in a mineral processing plant, are generally transferred to tailings ponds/impoundments to meet environmental regulations and site-specific factors before discharge. Most mining activities induce an impact on their geochemical environment (e.g., water, groundwater) due to the presence of metal-rich tailing deposits. The need for a comprehensive framework for mine tailings management that promotes sustainable development is therefore becoming increasingly recognized by the mining industry. Therefore, for sustainable rehabilitation and disposal of mining waste, the sources and mechanisms of pollutant generation and their subsequent effect on environment and sustainable treatment methods are critical. This review includes information on different sources of mining waters and its effect on groundwater contamination and ecological effects. The review also encompasses a broad range of mine water treatment strategies available for innovative management of mining tailings with a specific emphasis on the role of nanoparticles in the management of mine waters.

“…A rotating microfiltration membrane module was tested to enhance solids removal from AMD treatment for opencast lignite mining using a 2.0 m ceramic compact rotating disc (CRD) in cross-flow and dead-end set-up at transmembrane pressures between 1.2 and 1.9 bar (Meschke et al, 2015). The experimental results demonstrated the integration of a rotating membrane module into AMD treatment can remove iron hydroxide and enhance the solid content.…”

This review provides a snapshot of papers published in 2015 relevant to the topic of mine drainage generation and control options. The review is broken into 3 sections: Generation, Prediction and Prevention, and Treatment Options. The first section, mine drainage generation, focuses on the characterization of mine drainage and the environmental impacts. As such, it is broken into three subsections focused on microbiological characterization, physiochemical characterization, and environmental impacts. The second section of the review is divided into two subsections focused on either the prediction or prevention of acid mine drainage. The final section focuses on treatment options for mine drainage and waste sludge. The third section contains subsections on passive treatment, biological treatment, physiochemical treatment, and a new subsection on beneficial uses for mine drainage and treatment wastes.
